Medium: kernel

Issue Overview: A flaw was found in hw. Aliases in the branch predictor may cause some AMD processors to predict the wrong branch type, potentially leading to information disclosure. CVE-2022-23825 Non-transparent sharing of return predictor targets between contexts in some IntelR Processors may...

BSA-2022-2013

Security Advisory ID : BSA-2022-2013 Component : RETBLEED Revision : 1.0: Final A research team in Switzerland has found a new variant of the speculative execution vulnerabilities that affect some Intel and AMD chips aka RETBLEED. Retbleed CVE-2022-29900 and CVE-2022-29901 is the new addition to...

New Study Finds Most Enterprise Vendors Failing to Mitigate Speculative Execution Attacks

With speculative execution attacks remaining a stubbornly persistent vulnerability ailing modern processors, new research has highlighted an "industry failure" to adopt mitigations released by AMD and Intel, posing a firmware supply chain threat. Dubbed FirmwareBleed by Binarly, the information...

New 'Retbleed' Speculative Execution Attack Affects AMD and Intel CPUs

Security researchers have uncovered yet another vulnerability affecting numerous older AMD and Intel microprocessors that could bypass current defenses and result in Spectre-based speculative-execution attacks. Dubbed Retbleed by ETH Zurich researchers Johannes Wikner and Kaveh Razavi, the issue ...

CVE-2022-29901

Intel microprocessor generations 6 to 8 are affected by a new Spectre variant that is able to bypass their retpoline mitigation in the kernel to leak arbitrary data. An attacker with unprivileged user access can hijack return instructions to achieve arbitrary speculative code execution under...

CVE-2022-29900

Mis-trained branch predictions for return instructions may allow arbitrary speculative code execution under certain microarchitecture-dependent conditions...
